HERMAN MOTHER, OF NEW YORK, N. Y.

PENClL-SHARPEN ER.

SPECIFICATION forming part of Letters Patent N 0. 631,930, dated August 29, 1899.

Application filed March '7, 1899. Serial No. 708,092. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN EICHLER, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Pencil-Sharpeners, of which the following is a specification.

Reference is had to the accompanying drawings, in which Figure 1 represents the sharpener; Fig. 2, the method of using the same.

My invention relates to pencil-sharpeners which allow the pencil to be sharpened with the greatest ease and with the least degree of breakage to the point of the pencil. In most pencil-sharpeners the rotary motion of the pencil has a great tendency to force the cutting edge of the sharpener against the grain of the wood, thus often splitting the pencil and thereby breaking the lead. In my improved pencil-sharpener I avoid this by constructing the pencil-sharpener in such a manner as to give the pencil in the process of sharpening a perpendicular motion.

My sharpener may be made of any ordinary metal, preferably steel, in one piece. The one end is outwardly curved, as indicated by 2, the object being to provide a rest for the first finger of the left hand and to enable the sharpener to be more securely held during the process of sharpening the pencil. The other end is constructed with an outwardlycurved portion, as indicated by 5, said curved portion being made large enough to enable the pencil to be placed therein and freely moved up and down in sharpening, the object being to prevent the pencil from slipping out of the knife-edges 1 1 and also to give steadiness to the pencil while it is being sharpened. The part 5is curved outwardly from the point Where it joins the part 4.. The center portion of the sharpener between the curved parts, as indicated at 4., is thus given the appearance of being curved. The curved part 5 is also made with a V-shaped cut running downward from its upper edge, the sides of the said out being sharpened to k11ifeedges,which form the cutting edges of the sharpener.

In sharpening the pencil the sharpener is placed so that the first finger of the left hand rests in the curved part 2. The pencil is then placed between the knife-edges, being held by the four fingers of the right hand, the thumb resting upon the part 3 to give steadiness, and bya perpendicular motion of the four fingers is out to the point required.

Having thus described my invention, what I claim is=- A pencil-sharpener having an outwardlycurved end 2, the end 5, provided upon its upper surface with V-shaped cutting edges 1 1,

said end 5 being outwardly curved to admit the pencil being placed therein, and the flat surface 4, joining the parts 2 and 5, substan= tially as described.
